- The launch took place before the frequencies auction for the 5G technology of the National Telecommunications Agency (Anatel);
- Claro and its partners (Motorola, Ericsson, and Qualcomm) are going to disclose further details next week;
- The telecom carrier said that the additional spectrum, which will be auctioned by Anatel at a future date, will make it possible to expand the transmission capacity of the 5G network.
Claro, the telecommunications carrier owned by the Mexican América Móvil, announced on Thursday (July 2), the implementation of Brazil’s first 5G commercial network. The operator did not detail the area covered by the new network, but is using the frequencies it already had in previous generations of mobile networks, and applying dynamic spectrum sharing (DSS) to manage the network between technologies.
Claro’s new 5G DSS network uses Ericsson‘s Dynamic Spectrum Sharing technology to offer the fifth generation in the frequency bands available today. The smartphone Motorola Edge, in pre-sale by the carrier starting this week, supports DSS technology through its Qualcomm Snapdragon ™ 765 mobile platform and X52 modem.
The launch took place before the frequencies auction for the 5G technology of the National Telecommunications Agency (Anatel). The Brazilian frequencies auction, the largest in the world according to experts, was scheduled to take place in November, but Anatel representatives have already admitted that it may be postponed to December or even to 2021.
Claro and its partners (Motorola, Ericsson, and Qualcomm) are going to disclose further details next week. What the carrier stated in a press release is that, in addition to the regions that will be served in the initial deployment plan to be announced by Claro, the coverage of the 5G DSS will gradually grow in the coming years within the operator’s mobile network capacity modernization and expansion project.
“The additional spectrum, which will be auctioned by Anatel at a future date, will make it possible to expand the transmission capacity of the 5G network. By using higher frequencies than the current ones, the new spectrum bands allocated to 5G will require the deployment of a large number of antennas, to ensure coverage and capacity. The higher the frequency, the shorter the range, and the greater the need for signal transmission antennas,” explained the company.
Another necessary evolution in infrastructure, in this case to reduce latency, said Claro, will be the virtualization of network functions, with the decentralization of the core to data centers closer to customers, a technology known as edge computing. “The journey towards the final and expected 5G solution, therefore, will be a long one and will still require a lot of investment, and time for implementation across the country.”
The company informed that users who buy new smartphones with the 5G DSS technology will have connections 12 times faster than the conventional 4G.
The operator did not say which bands are being used for the 5G DSS technology, only that the network will use the frequencies already allocated to the Personal Mobile Service (SMP).
Anatel’s auction will mainly be in the 3.5 gigahertz (GHz) band, the most chosen band for 5G globally. According to the specialized Teletime and Mobile Time portals, the operator will use the same frequencies already applied in LTE-Advanced Pro, which aggregates the 700 MHz, 1,800 MHz (used for 3G), and 2.5 GHz (4G) bands (in addition to using multiple-input and multiple-output devices, known as 4×4 MIMO, that multiplies the capacity of a link using multiple transmission and receiving antennas).
